Sounds like you are doing a lot of "wondering" and questioning. That is a great thing, although it is kinda scary to face the unknown. You may feel like you want answers, and you want to tie it all up with a tidy little bow.... But I think it is a wonderful place right where you are! On the brink of self-discovery. I keep thinking of the Lady Gaga song, "I'm on the edge of glory, and I'm hanging on a moment of truth..."
I'm glad you are here. There are no easy answers, and many of your questions don't have hard-set answers, at all, anyway. You get to create your own life, wow, isn't that cool?! (I wish I'd done a better job of that at 25, myself). Enjoy the journey. You are right where you're supposed to be!
